The rotational incremental pressure-correction(RIPC)scheme,described in Timmermans et al.[***.,22(1996)]and Shen et al.[***.,73(2003)]for non-rotational Navier-Stokes equations,is extended to rotating incompressible *** method is implemented in the context of a pseudo Fourier-spectral code and applied to several rotating laminar and turbulent *** performance of the scheme and the computational results are compared to the socalled diagonalization method(DM)developed by Morinishi et al.[***.,22(2001)].The RIPC predictions are in excellent agreement with the DM predictions,while being simpler to implement and computationally more *** RIPC scheme is not in anyway limited to implementation in a pseudo-spectral code or periodic boundary conditions,and can be used in complex geometries and with other suitable boundary conditions.

Evaporative cooling is a widely used air cooling technique. In this method, evaporation of a liquid in the surrounding air cools the air in contact with it. In the current investigation, numerical simulations are carded out to visualize the evaporation and dynamics of tiny water droplets of different diameters in a long air duct. The effect of initial droplet size on the temperature and relative humidity distribution of the air stream in the duct is investigated. Three different initial conditions of air are considered to verify the influence of ambient conditions. Droplet spray patterns are also analyzed to identify the suitable locations for the spray nozzles within the duct. The resuits obtained are displayed in a series of plots to provide a clear understanding of the evaporative cooling process as well as the droplet dynamics within the ducts.

We report a new scheme for fabrication of clean,suspended superconducting weak links from pristine single-walled carbon nanotubes(SWCNT).The SWCNTs were grown using the floating-catalyst chemical vapour deposition(FC-CVD)and directly deposited on top of prefabricated superconducting molybdenum-rhenium(MoRe)electrodes by thermophoresis at nearly ambient *** contacts to SWCNTs were obtained by vacuum-annealing the devices at 900℃,which enabled proximity-induced supercurrents up to 53 *** weak links fabricated on MoRe/palladium bilayer sustained supercurrents up to 0.4 nA after annealing at relatively low temperature of 220℃.The fabrication process does neither expose SWCNTs to lithographic chemicals,nor the contact electrodes to the harsh conditions of in situ CVD *** scheme facilitates new experimental possibilities for hybrid superconducting devices.

目的：笔者以往的实验证明与猪抗原接触过并被CD4^＋T淋巴细胞激活的巨噬细胞能识剐、排斥猪的异种移植物，但不会排斥鼠的同种移植物，这表明在这种特异性移植物免疫识别及破坏过程中移植物及巨噬细胞之间存在着信号联系。方法：在免疫过继转移之前，将胎猪的胰腺碎片移植到非肥胖糖尿病／严重联合免疫缺陷（NOD／SCID）鼠。再从移植了胎猪的胰腺碎片（FPP）并发生排斥反应的受体Balb／c鼠身上分离出巨噬细胞，将这些外源性巨噬细胞植入NOD／SCID鼠。这些外源性的巨噬细胞通过Ly5．1表面抗原或通过CSFE染色标记来追踪。在移植了FPP异种移植物以后的CCR2，CCR5及它们的趋化因子的基因表达可通过实时PCR来评估。结果：形成免疫过继后较早移植的异种移植物出现了免疫排斥，而不是建立免疫过继较长时间后再移植FFP的NOD／SCID鼠。同时，前者可检测出更高水平的趋化因子的基因表达。而且，与未激活的巨噬细胞比较，已经激活的巨噬细胞CCR2，CCR5基因的表达增强更为明显。结论：趋化因子的上调与巨噬细胞的聚集、胰岛移植物的破坏有关。

房颤(AF)为冠状动脉搭桥术(CABG)后常见的并发症。尽管心脏外科术后AF发生较普遍,但其病理生理学机制仍未完全阐明。作者先前的研究表明,年龄及左房扩大为术后发生AF的独立预测因素。因此,本研究试图确定在术后发生AF的患者中是否发生细胞特性改变,如心肌纤维化和(或)心肌细胞肥大。对行择期CABG术的患者在心房切开时获取右心耳组织。
